Your priorities need a little realignment. Sweeping 5-10 should be your TOP priority. Dungeons are where the CC resources are kept.

Get Wally to 161e.

Team: Mike, PD, Cupid, Wally, Santa, Grimfiend.

Note: You might need Ghoulem and/or Heartbreaker for 5-10. Heartbreaker can also help you earlier in Insane 5, but don't work on her unless you find Santa insufficient. Rockno can also help in a pinch.
